Aircraft Ground Operations Simulator
Halamová, Mária ; Vlk, Jan (referee) ; Chudý, Peter (advisor)
This bachelor thesis is focused on designing an application which simulates the aircraft ground operations on Brno-Turany airport. It introduces a physical model of the aircraft ground motion over an airport infrastructure under various weather conditions. Considering Brno-Turany airport model, the application allows for motion trajectory visualization to avoid unwanted collision scenarios. The resulting ground motion trajectory display is a suitable decision support tool for the air traffic and ground controllers.

Climate testing room for personal vehicles
Málek, Ludvík ; Katolický, Jaroslav (referee) ; Štětina, Josef (advisor)
The diploma thesis deals with the design of testing equipment, a climate chamber in particular, to simulate external weather conditions. The chamber walls are made of socalled sandwich insulation panels. Based on the wall thermal properties, heat loss of the chamber was calculated. The conditioned air is supplied by a distribution channel at sides of the chamber. The exhaust air leaves the chamber in the ceiling zone. The ventilation unit is located on the ceiling. The design includes the integration of the UV lamp, simulating sunlight. The chamber will allow the weather effects on the microclimate inside a car to be studied. Furthermore, the sunlight simulations can be carried out in the chamber to detect polymers or varnish aging, and the fading of colours.

Surface treatment for resistance improve of board materials with cement matrix and an organic filler
Zrza, Ondřej ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
As all materials used for exterior construction, cement-bonded particleboards also subject to climatic effects, such as frost, chemicals (eg. sulphates) or UV rays. Degradation of theese effects is slightly increased by organic base. Increased susceptibility can be eliminated by a effective coating, which reduces direct contact with aggresive influences on the board and provides longer durability. Theoratical part of this thesis analyzes different types of negatice influences and their effect on durability. Practical part contains selection of specific types of coating and assessment of their mechanical and aesthetic properties including spectrophotometric analysis of color change for each degradation effect.

Vyhodnocení efektivnosti aplikace dusíku v minerálních hnojivech při pěstování ozimé pšenice
Ovchinnikova, Tatiana
The aim of the diploma thesis was to evaluate the effectiveness of nitrogen application in mineral fertilizers in winter wheat cultivation. The results of an international competition on crop management practices of this crop conducted at the Agricultural Research Institute Kromeriz, Ltd. in the years 2014-2018 were processed. A total of 279 variants of crop management practices were compared in small plot field experiments (2014-46, 2015-51, 2016-56, 2017-64, 2018-62). The indicators chosen for evaluation were the total nitrogen dose (kg/ha), grain yield (t/ha) and crude protein content in the grain (%). Grain yields were significantly influenced by the weather conditions in each year. In all years, with decreasing total nitrogen dose, the variability of grain yield gradually increased. A significant increase in grain yield variability was observed for total nitrogen doses lower than 140-150 kg/ha N. Nevertheless, some variants of crop management with low nitrogen doses achieved yields comparable to variants with a total nitrogen dose higher by 50-60 kg/ha N. These economically beneficial results were achieved by optimizing all cultivation measures during the crop management in accordance with the properties of the cultivated variety and the course of the weather. A reduction of nitrogen consumption by 50 kg/ha, reduces the risk of nitrate contamination of the environment and also represents a saving of CZK 2,714/ha, at the average price of nitrogen of CZK 54.3/kg in commonly used mineral fertilizers in 2022. The change in nitrogen doses also affected the content of crude protein in the grain. In all years, a negative relationship was found between the yield and crude protein content in the grain. With an increase in grain yield by one tonne per hectare, the crude protein content in the grain decreased by 0.12-0.35%, and on average by 0.24%.

Pilot testing of LoRaWAN technology in disconnecting fuse boxes
Benešl, L. ; Mlýnek, P. ; Harman, D.
This article deals with the concept of Smart Cities concerning Smart Grids. As part of Smart Grids and secondary metering, there is also the lifespan of the devices that are deployed in distribution companies. This also applies to switch cabinets, disconnecting fuse boxes (DFB), and other elements that are made of a material that can degrade due to adverse weather conditions. For this reason, secondary temperature and humidity measurements have been introduced. During the measurements, temperature extremes were recorded, which could reach more than -10 °C in winter months and almost 45 °C in the warm months. Humidity could reach up to 100 % in some cases. Another monitored parameter was the successfully received messages, where LoRaWAN technology reached almost 95 %.
